We joined the English-speaking tour, and our guide, Caliche, was very professional. Before we set off, he thoroughly explained how to use the bicycles and covered all safety precautions, ensuring every participant was comfortable riding before we departed. Along the way, he meticulously looked after everyone, ensuring our safety amidst the busy traffic. He also shared interesting anecdotes at various historical sites and took photos of each member at every photo spot, allowing us to discover unexpected views. The only minor drawback was that to accommodate everyone's cycling abilities, we didn't have enough time to visit Lawrence Market. Overall, cycling through the city's main attractions in half a day gave us a good overview of the city, saved us a lot of walking, and was very time-efficient. It's definitely worth experiencing.
